VALVE.

SPECIFICATION forming part of Letters Patent N 0. 762,436, dated June14, 1904.

Application filed September 29. 1902. Serial No. 125,277. (No model.)

To all whom, it may concern:

Be it known that I, ALFRED G. Oseoon, a citizen of the United States ofAmerica, residing at Athol, in the county of lVorcester and State ofMassachusetts, have invented new and useful Improvements in Valves, ofwhich the following is a specification.

the valve-casing of sediment, debris, or im-' pedimenta, the presence ofwhich would prevent the free action or working of the valves.

A further object is to provide an implement, device, or apparatus of thekind named Which is simple in construction, efiicient in action, anddurable in use, all as hereinafter will be fully specified, and thenovelty thereof particularly pointed out and distinctly claimed.

The invention embodies a suitable casing adapted to be interposedbetween and secured to the approaching ends of mains, pipes, and similarconduits, seats formed in the casing, cleaning or clearing devices ormechanism, and valves or gates to open and close the mouth of theconduit-passages I have fully and clearly illustrated the invention inthe annexed drawings, to be taken as a part of this specification, andwherein similar reference designations indicate like parts appearing inthe several illustrations, and ref erence being bad to said drawings-Figure 1 is a central longitudinal vertical section through the device,showing the valveseats, the valve-block, and associated valves and meansfor opening and elosingthem. Fig.

2 is a vertical section taken transversely through the valve-casing onthe line 2 2 of Fig. 1, showing the valve-block raised and the cleaningor clearing member. Fig. 8 is a detail sectional view showing thevalve-block and the channels in which the inclined gate andactuating-stem engage. Fig. 4 is a detail perspective view of themovable member of the clearing device. Fig. 5 is a view in elevation ofthe movable clearing device arranged in its casing in the lowerposition.

A designates the valve chamber or casing, of suitable capacity to meetthe purposes intended and formed with end extensions 1 2, havinginterior screw-threads in which the threaded ends of the pipes 3 3engage, as shown in the drawings. The upper face of the easing is plainand square, and fitted to the surface and suitably secured thereto is acap-piece or head 4:, having a chamber into which the valve lifts, asshown in Fig. 1 of the drawings. In the bottom of the casing is formed adish-shaped or circular depression 5, affording a receptacle or trap forthe deposition and retention of any substance which may find lodgmenttherein. Above the receptacle 5 is formed a circular flange 6, arrangedat an incline coincident with the incline of the valveplate which coversthe water opening or passage and provided with internal screw-threads,with which the threaded perimeter of a ring 7 engages. The ring 7 isformed with an annular fiange 8, which laps over and rests upon theupper face of the circular flange 6, as shown in the drawings in Fig. 1,and constitutes the seat for the inclined valve. The end of thevalve-chamber opposite to the inclined valve-seat is vertical and planedsmooth and formed with a suitable circular water-passage, the walls ofwhich are provided with screwthreads, with which a threaded ring 9engages and constitutes the valve-seat for the vertical valve-plate.

B designates the valve block or body, having at one end a vertical.plane and an inclined surface at the other end. In the upper face ofthe valve-block is formed an open-end T- groove 10, in which a T-shapedfoot 11, formed on the lower end of the valve-stem 12,engages. Thevalve-stem has threaded engagement in the vertical neck 13 of the heador cap 4, whereby the valve-block with the valves may be reciproeated inthe usual manner. A handwheel 14 is fixed to the stem to operate thevalves, and a threaded cap 15, with the valvestem slidingly projectedtherethrough, engages over the upper end of the neck 13, as

shown. In the inclined surface 16 is formed an open-end T-groove 17, inwhich the T-head 18, projecting from the back of the valveplate 19, isdetachably posited. The valveplate 19 is made of brass or other suitablemetal and fits down tight on the valve-ring 7 and closes the port orpassage. On the vertical working end of the valve-block is secured aplate 20, made of brass or other proper metal. The plate 20 has thelower end rounded, as shown, so that it will make proper workingengagement with the movable member of the clearing device and pass downinto the circular recess or channel in the casing and close against'theouter wall of the recess.

From the foregoing description, taken in connection with theillustrations, especially Fig. 1, it will be perceived that in thedownward movement of the valve-block, the valveplate 20 passesvertically in contiguity with the vertical end surface of the bushing orvalve-ring 9, located in the mouth of the conduit 3, and that theinclined valve or plate moves downward at the same time; but because therounded end of plate 20 extends a short distance farther down than theclosing face of the. inclined valve the mouth of the pipe 3 is closed bythe plate 20 before the inclined valve is fully seated. Thus thepressure is taken off the inclined valve at the moment of its closing,and any sediment contained in the water will by reason of theimpingement thereof against the inclined face of the valve be depositedin the trap 5 and by reason of the cup-shaped form of the latter bewashed out when the valve is next opened. It will also be perceived thatwhen the valve is lifted the force of the current will sweep anyaccumulation in the trap out and carry it through the pipes.

In the valve-easing contiguous to the vertical wall of the casing isformed a curved or circular channel 21, disposed transversely to theaxis of the casing, and, as stated, into this channel thelower roundedend of the valve extends, and thus completely shuts off the water. Suchchannels or their equivalents are common in the art to receive the valveor the edge portion thereof, and under ordinary circumstances dirt,sand, or pebbles lind their way into the channel and eventually resultin preventing the full and complete closing of the valve and also grindand deface the face of the valve. To prevent detrimental deposition ofdebris in the channel and to remove such as may have found lodgmenttherein, I have devised and provided the following-described mechanism:The clearer or cleaner is lodged in said channel between the end of thecasing and the inner wall of the channel, on which is formed a flange22, the vertical side walls or extensions of which are broadened, asseen at 23, to extend inward and serve as guides and stays to preventthe valve-block from turning inward or assuming other displacement inoperation and while being seated in its lower position.

Reference being made tothe drawings, 24 25 designate a two-part U-shapedcasing, the part 24 being made of a metal plate formed with an edgeflange 26 at right angles to the body of the plate and locking-pieces27, which extend beyond the edge of the flange 26 to engage against theinner faces of the companion part of the casing and hold the twosections in position in alinement. At the upper ends of the part 24 areformed angle-pieces 28, which extend over the mouth of the parts orsections, and at the outer part of the upper ends are formed lateralopenings in which the inclined pieces or lugs of the movable mem-- berof the cleaner engage. The part or section 25 of the cleaner-casingconsists of a counterpart in general conformation and sets or restsagainst the other, the distinction being that the part 25 has plainupper ends and in its central lower portion has a vertical guidepiece29, which guides the vertical movements of the movable cleaning member.

30 designates the movable member, consisting of a bow-spring 31, havinga guide-notch 32 at the middle, which takes in the guide piece 29 of thecleaner-case. To the upper ends of the spring are formed or fastenedinclined lugs 83, the outer parts of which snap through the lateralopenings at the upper ends of the cleaner-casing and hold the cleaner inits upper position, and when the cleaner is moved down the outer ends ofthe lugs bear the arms of the spring inward and force the inner lugsinto engagement with the recesses.

The inner and lower projections of the inclined lugs 33 are formed withsquare or abrupt under faces, so that when the valves are pushed down totheir lower and closed position and carry the cleaner down on themovement the inner parts of the inclined lugs will engage in notches orrecesses 34, made in the side edges of the vertical valve-plate 20, andthus held the cleaner will be drawn upward when the valves are lifteduntil the position is reached which brings the outer parts of theinclined lugs free to enter the lateral openings at the upper ends ofthe cleaner-casing, when the action of the spring will spread the lugsapart and release them from their hold in the valve and force them intoengagement in the said openings, and so hold the spring as covering thechannel and preventing any substance from entering it.

It may be stated that under some circumstances the cleaner-casing may bedispensed with, especially when the valve-casing consists of anon-corrodible metal, in which instance the recesses will be formed inthe wall of the channel into which the outer ends of the lugs 33 willengage.

The action or operation of the mechanism may be stated as follows:Assuming that the valves are in the .upper position, as seen in Figs. 1and 2 of the drawings, and it is desired to close the way, the valvesare moved down by the action of the threaded stem until the lower end ofthe vertical valve engages the bow-spring, and then by continuing themovement the cleaner is carried down with the valve-block to the limit,when the lugs of the spring engage the recesses in the valve and thereremain until the valve is lifted. When the valve is lifted, it raisesthe cleaner with it until the lateral openings in the cleaner-casing arereached, when the lugs are moved therein and released from the valve,which may then be raised to the upper position.

hen the cleaner has been raised as indicated in Fig. 1, it stands as aguard bridging the channel and prevents the lodgment of any matter whichin the absence of the guard or cleaner would find its way into thechannel.

It may be desirable or essential to mount the casing in invertedposition, in which position during the movement of the inclined valve itmightslip in its connection to the valve-block, and to prevent this Iform in the cap or head 4 a vertical rib 35, against which the edge ofthe inclined valve bears and is kept in proper relative position.

Having thus described my invention, what I claim is 1.
